Abstract

The invention relates to a method for determining the stability of a layer of foam on a liquid column, for example beer, by measuring the time interval during which a surface of the layer of foam moves a certain distance under particular circumstances, which time interval is subsequently compared with a reference time interval associated with said distance. The invention also relates to an apparatus for carrying out the method according to the invention. The method according to the invention is characterized in that at least one external environmental quantity is registered during the movement of the foam surface and that after the time interval has been measured the registered external environmental quantity is used for correcting the measured time interval. <IMAGE>
